Architectural support for register allocation in the presence of aliasing. A hardware support mechanism is presented that permits all classes of data objects, including dynamically allocated objects and array elements, to be held in registers without consideration of … Expand.

This returned value contains the physical address of the logical page and an access code to indicate its presence in main memory. Associative memory registers are very expensive so only the most frequently accessed pages should be represented by them. How many associative memory registers are required for a virtual memory implementation to run efficiently?

The effective access time of the virtual memory system can be computed by multiplying the hit ratio by the access time using associative memory and adding 1 - the hit ratio times the access time using the main memory page table. The following diagram can represent the relation between the memory array and the external registers in an associative memory.

The cells present inside the memory array are marked by the letter C with two subscripts. The first subscript gives the word number and the second specifies the bit position in the word. For instance, the cell C ij is the cell for bit j in word i. If a match occurs between all the unmasked bits of the argument and the bits in word i , the corresponding bit M i in the match register is set to 1. If one or more unmasked bits of the argument and the word do not match, M i is cleared to 0.
